Specification of Letters Patent. P t t d t, 14,

Application filed April 21, 1909. Serial No. 491,375.

I To all whom it may concern:

Be it known that we, J ULIUs-KAHN, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, and THOMAS H. KANE, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented a new and useful VVindow- Frame, of which the following is a specification.

This invention relates to metal supports for window lights, and its object is to pro- Vide windowframes which shall be of great stiffness for'the amount of metal employed, and which shall be of pleasing appearance.

.In the accompanying drawings, Figure 1 is an outside elevation of an assembled wintwo connected sashes.

dow frame having a hinged portion adapted to be swung open. Fig. 2 is a cross section of one type of frame on the line 2-2 of Fig. 1. Fig. 3' is a cross section of the same type of construction on the line 3-3 of Fig. 1. Fi 4 is a cross section of a slightlym'odifie form of construction on the same line 33 of Fig. 1. Figs. 5 and 6 are cross sections of two modifications of construction on the line 66 of Fig. 1. Fig. 7 is a cross section of the type shown in Figs. 2, 3 and 6 .on the line 77 in Fig. 1. Fig. 8 is a cross section of the same type on the line 8--8 in Fig. 1. Fig. 9 is an elevation of the hinge. Fig. 10 is a view of an individual sash bar on a smaller scale. Fi 11 is a view of igs. 12 and 13 are views of frame bars. Fig. 14 is a cross section of a frame bar. Fig. 15 is a perspective.

view of the end of a rib.

Similar reference characters refer to like parts throughout the several views.

The present construction consists of a series 0 sashes, one for each pane of glass,

united by side bars and ribs Into a frame.

The different parts are secured together by rolling down projecting flanges so that but a minimum amount of machine work is necessary. For safety, the parts may be united by electrically welding-adjacent portions. I i

- .TWo types. of construction and modifications of the types are shown. Each pane will be. secured in a separate sash, formed from a generally T shaped bar such as is shown atl, Fig. 10, one flange of which is notched and which bar is bent to. form; the. sash in Fig. 11. Two sashes may be connected by Tongues 6 are cutof the bars, and after the glass IS in position,

in the drawings, and the rolled down.

. which form an air s age between and the building wal s, 1n which mortar may in Fig. 11. The bars may have any desired cross section. In Figs. 2, v3, 6, 7, and 8 the bar has three flanges 3, 4 and .5, the flange 3. being at right angles to flanges 4 and 5.

rec from the flanges 4 these tongues may be bent out, as indicated glass thereby held e used if desired. The position of the flange 3 will determine whether the glass shall be central or nearer one side. It is obvious that the putty s1de of the sash may be toward either the weather or the interior. The form of bar 8, shown in Fig. 5, is that especially adapted for saghes where the glass 9 is to be near one s1 e.-

The edges of the flanges 4 and 5 are preferably beveled to properly provide engaging portions for the ribs and frames. The r bs in position. Putty 7 may are preferably in the form of I beams 10,

having a web and flanges 1]. as

(Fig. 3) shown in Figs. 3 and 15. The sashes are placed within the flanges and these are then This unites adjacent sashes and by placing the ribs vertically in the assembled construction, great stiflness results.

The ends 12 of the ribs are so formed that they may be slipped into the slots 13 in the.

upper and lower bars 14 of the outer frame. The side bars 15 of the outer frames also have tongues 16 which enter slots 13 and are riveted over. In this manner the outer frame and the ribs will be firmly. united. The frame barshave flanges 17 which receive the bars 1, which flanges are rolled down to secure the parts together as shown in Fig. 2. They may also have flanges 18 the frame be run, if desired, to hold the frame in the window opening. I

It is sometimes desirable that a portion of the window frame can be swung open for ventilation. In Fig. 1, the six middle sashes are united into an auxiliary frame which may swing on a central horizontalaxis. The details of the construction are shown in Figs. 7 8 and 9. The sash bars have the usual electrically welding at points 2 as indicated flanges 3, 4 and 5. Instead of using the frame bars 14, the side members '20 ar preferably small I beams... The adjacent flanges of the I beams are cut away at the pivots and hook plates 2-1 areattached to these side members by the jaws 22 which are secured in position by the bolts 23. A pivot 24 is the opening, with the flange 26 on the inside, while this flange of the upper stationary bar will be on the outside. See Fig.

1. Thus when the window'is closed, the

cracks between the stationary and auxiliary frames will be closed by two flanges 26, one

- onthe outside, the other on the inside. The

)yes,

' of wind pressure,

flanges 11 of the beams 20 are rolled down over the beveled edges of the bars 25 and thus secure them in position.

Instead of the compact constructions above described, the parts maybe so formed that air-spaces will separate portions of the frames. In Fig. 4, the rib 27 is shown with a web and'grooved flanges 28, which flanges are rolled down to properly engage the sash bars 29, and form lar e air spaces between the web of the rib an the sash bars. The flanges 30. of the sash bars may also be grooved to form an air-space next to the lass. I

The flanges on the various bars may be beveled as shown on the lower end of the rib in Fig. 3, or they may be leftv of even thickness throughout in order to furnish shoulders to support the putty as shown in all the other portions of the drawings. I

It maybe desirable to have the bars 20 of the swingin auxiliary frame extend entirely around this frame, in which case this bar will be bent at the corners. After the frame is assembled, the flanged bars 25'are positioned and the outer flanges of the I eams'20 are rolled :down. Thehinge may be first secured to either the stationary or auxiliary frame before the auxiliary frame 1s secured in proper position.

As each rib and side member of the frame a window must act as a girder to resist it is of the utmost importance that the full strength of each be preserved, and that intimate union exist between the parts. By giving the ribs and side bars the forms of I beams the greatest strength is attained for the amount of metal emp lo ed. By rolling down the flanges to secure y grip the ed es of the sash bars the whole frame is ren ered practically -..equal toan integral construction.

Having now explained our improvements,

v what we claim as our invention and desire 'to' secure by Letters Patent is 1. Ina wlndow frame construction, thean opening in the main frame,
